PRODUCT DESCRIPTION     
One component polyurethane waterproof coating is a liquid elastic waterproof coating with polyether polyols as the basic component and non tar asphalt additives as additives. It solidifies upon contact with water vapor in the air, forming a flexible and strong seamless overall waterproof film on the surface of the base layer. The coating has a very good bonding force with the base layer such as concrete, which can effectively prevent water from flowing under the waterproof coating. Its inherent flexibility can resist any possible structural deformation and shrinkage cracks.

PRODUCT FEATURES

▪ Fast construction speed can shorten the construction period
▪ High strength, high elongation, high elastic recovery rate, and strong adaptability to cracking and expansion of the base layer.
▪ Low temperature flexibility is very good.
▪ Strong adhesion to the base layer, no need to apply base treatment agent.

CONSTRUCTION TECHNOLOGY   
Grassroots treatment:
▪ The grassroots must be flat, firm, clean, without visible water, and the internal and external corners should be made into circular arcs;
▪ The old roof should have the original cracked and bulging waterproof layer and dust removed, and the low-lying and damaged areas should be leveled;
▪ Leak prevention measures must be taken first, and the base layer should be flat without any visible water;
▪ Special areas such as water outlets and dividing joints should be first treated with flexible sealing;
▪ The painting process usually starts with the internal and external corners, then the vertical surface, and finally the large-scale construction.
Bottom coat construction:
▪ Mix water and paint in a 1:3 weight ratio, stir evenly before use;
▪ The use of primer can improve the permeability of the coating to the base layer and enhance the bonding strength.
Apply paint:
▪ The construction can be carried out by rolling, scraping, or brushing methods, and it is advisable to use the thin layer multiple coating method. Each coating should not be too thick;
▪ Generally divided into 3-4 coats, with a total thickness of 1.5-2.0mm;
▪ After the coating dries and forms a film, the next coat of paint can be applied;
▪ Weak links should be reinforced with tire body materials.
